Self-healing polymer composition and associated uses

Abstract

A self-healing polymer composition includes a polymer backbone having at least one amine terminated end group. The polymer backbone is selected from the group consisting of a polymerized siloxane and an aliphatic polyether and preferably polydimethylsiloxane. A cross-linker is selected from the group consisting of a 1,3,5-triarylbenzene, a triaryl-amine and 2,4,6-trichloro-1,3,5-benzenetricarbaldehyde, and preferably is 1,3,5-tris-(4-formylphenyl) benzene.

1 . A self-healing polymer composition, comprising:
 a polymer backbone having at least one amine terminated end group, wherein the polymer backbone comprises a polymerized siloxane having a molecular weight of 290 to 16,000 gmol −1  and comprises polydimethylsiloxane (PDMS) and having at least one amine terminated end group;   a cross-linker comprising 2,4,6-trichloro-1,3,5-benzenetricarbaldehyde; and   silicon nanoparticles embedded in the polydimethylsiloxane and cross-linker forming the composition that improves the hydrophobic properties of the composition.
